The study of surface decontamination of radioactive waste packages is an important project for EDF in the context of decommissioning. This study has two objectives: firstly, to reduce dosimetry due to the control of non-contaminated area of radioactive waste packages and secondly to ensure the non-contamination of surface parcels as they are sent to their final destination (treatment site and/or storage). This serves to avoid the suspension and the filling of labile activity in the transport of packages that could lead to locally exceeding the regulatory surface contamination threshold. For that purpose, a bibliographical study of the methods of decontaminations proposed in the literature was made. This study allowed seeing if techniques could answer the chosen criteria. Techniques seeming to be able to answer the requirements were then tested to estimate their efficiency. The bibliographical study and the tries of qualification showed that a method seemed more adapted than the others to our problem.
